Describe the bug

gpt 3.5/4o model raises error code 500 when the message history 1) contains multiple, different tool calls with name field., 2) contains multiple user messages from different users

For example

[
   textMessage("what's weather in Paris", from: "user")
   toolCall(getWeather, Paris, name: assistant)
   toolCallResult("the weather in Paris is sunny")
   textMessage("The weather in Seattle is sunny, now check the tax in Paris", from: "admin"),
   toolCall(calculateTax, Paris, name: assistant)
   toolCallResult("the tax in Paris is xxx")
   textMessage("what's weather in Beijing", from: "user")
   toolCall(getWeather, Beijing, name: assistant)
   toolCallResult("the weather in Beijing is sunny")
   textMessage("The weather in Beijing is sunny, now check the tax in Beijing", from: "admin"),
   toolCall(calculateTax, Beijing, name: assistant)
   toolCallResult("the tax in Beijing is xxx")
   textMessage("what's weather in Seattle", from: "user")
]

// error code: 500

According to https://community.openai.com/t/error-the-model-produced-invalid-content/747511, the model can respond correctly after the name field is removed when the assistant message is a tool call message
